APARATUS FOR THE MANUFACTURE GI HYDROGEN;

To all mag/concern Y Be itknown thatV I, FRIEDRICH BERGIUS,

' a citizen of the German Empire, residing at Hanover; Germany, have invented certain new and useful Improvements In Ap aratus for theV Manufacture of Hydrogen, o which -the following is a specification.

This invention relates to an apparatus' *for the manufacture of hydrogen in accordance with the specification led August2'6,

1912, Serial No. 717,202.

-In the closed vessel in which water, heated in a liquid state to a point beyond the boiling point, is acting on the metals, there is produced', in addition to hydrogen, steam,

.from which the hydrogen must be separated if 1t is'notdesired to ,evaporate'in' a useless manner quantities of water and thus suffer losses of heat. AIn order to 'discharge from 'the heated apparatus the hydrogen gener ated, without any steam, above the reaction Achamber is arranged a gas chambermaint-ained at' a lower temperature, in which the steam 4rising with 'the y hydrogen', is condensed, while the hydrogen gradually completely v'fills vthe chamber and prevents any further admission of steam, as iti is in highly compressedstate. The blow oif valvefor the hydrogenis at a point at which the pure hydrogenv has collected.4 The invention is. explained in the drawing lshowing diagrammatically the appara.- tus.

The reaction vessel a which is preferably made of compressed steel, like carboys, and

. in the surrounding spae u of which there is a temperature of about 300 C., is adjoinedl i Specification of- Letters Patent.k

Batented Apr. 22, 19.13.

atl-.the .top by a gaschamber b, the surrounding space of whichis maintained in any desired manner at a lower temperature. A emovable plug e through which passes a ,tube f closes the bottom of the vessel. Iron or a low iron oxid or in some cases a more precious metal, for. instance copper, maybe `electrolyte such as common salt, iron chlorid,

small quantities of hydrochloric acid, are introduced into the Ivessel through the tube f. The mixture of steam and hydrogen rising from the tank arises in the tube b in -which the steam is condensed and drips back into the vessel av in liquid form. As the process is going on, more andmore hydrogen collects in that way in the chamber b, which hydrogen is at a high pressure up to more than 100 atmospheres'.

The blow off valveis at 0.

What I claim is Y Anapparatus for manufacturing hydrogen, comprising =abulb-shaped retort, a closure in the bottom constituting means to admit material to be acted upon, means through said closure to admit a hydrogencontaining Huid, a condensing' extension pro' jecting upwardly from said retort, an outlet=pipe from said extension, and a valve closing said extension` and outlet pipe.

In testimony whereof I ax my signature in presencev of two witnesses.
